Ladies and gentlemen, for your viewing and listening pleasure, it’s the fourth installment of “Symphony of Science.” If you missed the first three iterations of John Boswell’s creation, he auto-tunes the syncopated scientific stylings of Carl Sagan’s monologues from “Cosmos,” combined with guest stars like Stephen Hawking, Neil deGrasse Tyson (of DISCOVER’s StarTalk podcast, among many other media ventures), and Richard Feynman. If you need to catch up, all four are available on Boswell’s site. The first can even be had on vinyl through the label of the White Stripes’ Jack White—Third Man Records.
